Abstract
The pour point of a hydrocarbon charge stock boiling in the range of 400.degree. F. to 1050.degree. F., and particularly a lubricating oil charge stock boiling between 600.degree. F. and 1050.degree. F. is reduced by catalytically dewaxing the charge stock in the presence of a zeolite catalyst and subsequently subjecting at least the liquid portion thereof to hydrotreating in the presence of a hydrotreating catalyst comprising a hydrogenating component and a siliceous porous crystalline material from the class of ZSM-5, ZSM-11, ZSM-23 and ZSM-35 zeolites.
